The State Government has announced a Local Land Services organisation will replace the 14 LHPAs, 13 Catchment Management Authorities and part of the Department of Primary Industries from 2014.

An independent review released earlier this year recommended the merger.

The chairman of the LHPA State Management Council, Ian Donges, says jobs should be safe for the next 15 months at least.

"It doesn't talk about staff changes at LHPA, and it doesn't talk about budget cut backs, so from my perspective it will be business as usual for the period leading up to the first of January 2014.

"After that a whole lot of things may happen, but at this stage it's too early to speculate on what they may be."

The State Government has confirmed the change will see job losses in the Department of Primary Industries.

Mr Donges says he can understand people being wary of the change, following the last restructure in 2009.

"That's because there was so many people impacted last time, directors and rate payers, and a whole range of people were impacted last time.

"We don't know exactly where this new organisation will come out in terms of that impact again on those people."

The New South Wales Farmers' Association says it is cautiously optimistic about the merger.

The President, Fiona Simpson, says having one organisation should streamline service provision.

"At the moment out in the state we have a variety of bodies providing a variety of services, some of these services overlapping and duplicating.

"I think we do see an overlapping of resources sometimes with the way that these different bodies operate."

She says the merger should not be judged on whether it involved job cuts.

"Look our members would always be concerned about reductions in services, but I think that's the critical point here, it's not about numbers on the ground necessarily, it's about how those services are delivered and the efficiency of how those services are delivered."
